City's PM10 levels drop 12% in seven years
According to the data presented by Ministry of Environment, Forest and Climate Change in the Lok Sabha, the average concentration of PM10 levels in Chennai dropped by 12.1 % from 66 µg/m3 in 2017-18 to 58 µg/m3 in 2024-25.
Thoothukudi, meanwhile, recorded a 54.5% reduction with the PM10 levels dropping from 123 µg/m3 in 2017-2018 to 56 µg/m in 2024-2025. The average concentration of PM10 levels in Madurai and Tiruchy dropped from 88 and 72 in 2017-18 to 57 and 61 in 2024-25 respectively.
Meanwhile, Chennai fared poorly in terms of drop in PM10 levels compared to other metropolitan cities like Mumbai (44%), Kolkata (37%), and even Delhi (15.8%). However, in terms of the actual average concentration of PM10 levels recorded, Chennai with 58 µg/m3, fared far better than Mumbai (90), Kolkata (92), and Delhi (203).
Although Chennai is now closer to the National Ambient Air Quality Standards (NAAQS) of 60 µg/m3, experts say the progress is incremental and insufficient given the scale of urbanisation, traffic, and construction activity.
'The figures may look acceptable on paper, but the health impact remains tangible. We continue to see rising respiratory cases in urban centres like Chennai,' a senior pulmonologist at the Rajiv Gandhi Government General Hospital told TNIE.

ICMR study found Covid vaccination didn't raise risk of unexplained sudden deaths among young adults: J P Nadda
New Delhi: An ICMR study has found that Covid vaccination did not increase the risk of unexplained sudden deaths among young adults in India, Union Health Minister J P Nadda told Lok Sabha on Friday. Past Covid hospitalization, family history of sudden death and certain lifestyle behaviours increased the likelihood of unexplained sudden deaths. Responding to a question, Nadda said the Indian Council of Medical Research (ICMR) has informed that it and the National Centre for Disease Control (NCDC) explored two approaches to investigate the causes of sudden death. The first approach was a retrospective case-control study to determine the risk factors associated with sudden death and the second approach of the study was to prospectively investigate sudden deaths in young adults using a virtual autopsy approach. The ICMR-National Institute of Epidemiology (NIE) conducted a study titled "Factors associated with unexplained sudden deaths among adults aged 18-45 years in India - A multicentric matched case-control study" at 47 tertiary care hospitals located across 19 states and Union territories during May-August 2023. Cases were apparently healthy individuals without any known co-morbidity, who suddenly (less than 24 hours of hospitalization or seen apparently healthy 24 hours before death) died of unexplained causes during October 1, 2021-March 31, 2023, Nadda stated. Four controls were included per case matched for age, gender and neighbourhood. Information was collected regarding data on COVID-19 vaccination/infection, post-Covid conditions, family history of sudden death, smoking, recreational drug use, alcohol frequency, binge drinking and vigorous-intensity physical activity two days before death among the cases or interviewed controls, he said. A total of 729 sudden death cases and 2916 controls were included in the analysis. It was observed that receiving two doses of Covid vaccine significantly reduced the odds of unexplained sudden death, Nadda stated. Past COVID-19 hospitalization, family history of sudden death, binge drinking 48 hours before death/interview, use of recreational drug/substance and performing vigorous-intensity physical activity 48 hours before death/interview increased the odds of sudden death. "Hence, the study observed that COVID-19 vaccination did not increase the risk of unexplained sudden death among young adults in India. Past COVID-19 hospitalization, family history of sudden death and certain lifestyle behaviours increased the likelihood of unexplained sudden death," he said. The second study, titled "Establishing the cause in sudden unexplained deaths in young" conducted by the All India Institute of Medical Sciences (AIIMS), Delhi with funding and in collaboration with ICMR, is a prospective work aimed at determining the common causes of sudden deaths in young adults. Early analysis of data from the study indicates that heart attacks, or myocardial infarction (MI), continue to be the leading cause of sudden death in this age group. Importantly, no major changes in the pattern of causes have been observed when compared with previous years before the Covid pandemic. Together, these two studies offer a more comprehensive understanding of sudden unexplained deaths in young adults in India, Nadda said. It has also been revealed that Covid vaccination does not appear to increase the risk, whereas, the role of underlying health issues, genetic predisposition and risky lifestyle choices does play a role in unexplained sudden deaths, he said.

Over 14K Anganwadi cum crèche approved in the country, highest in Chhattisgarh: Minister
NEW DELHI: A total of 14,599 Anganwadi cum Crèches (AWCCs) have been approved by the Centre, the Lok Sabha was informed on Friday. In a written reply, Minister of State for Women and Child Development, Savitri Devi, said these AWCCs will ensure full-day childcare support for children, thereby ensuring their well-being in a safe and secure environment. The Anganwadi cum Crèche initiative aims to increase women's workforce participation in the economy. The maximum number of AWCCs set up so far are in Chhattisgarh (1,500), Meghalaya (1,238), Telangana (1,033), Jharkhand (1,024), Odisha (1,000), Manipur (702), and Tamil Nadu (600). The minister said that Anganwadi centres are the world's largest childcare institutions, dedicated to providing essential care and support to children, ensuring delivery of childcare services up to the last mile. In a first-of-its-kind approach, the Ministry of Women and Child Development has extended childcare services through the Anganwadi cum Crèche (AWCC) initiative. The objective of the Palna Scheme is to provide quality crèche facilities in a safe and secure environment for children (aged 6 months to 6 years), along with nutritional support, healthcare, cognitive development, growth monitoring, and immunization. Crèche facilities under Palna are provided to all mothers, irrespective of their employment status. 'During the 15th Finance Cycle, i.e., up to FY 2025–26, a total of 17,000 Anganwadi cum Crèches (AWCCs) are envisioned for establishment under the Palna Scheme. Proposals for the establishment of AWCCs are received from the respective state governments/UT administrations, who also contribute their corresponding share for the implementation of the scheme. Till date, a total of 14,599 AWCCs have been approved by the Ministry as per proposals received from various States/UTs,' Devi said.
